[Elecraft] Elecraft W2 Wattmeter for sale ... needs repair

I have a W2 wattmeter with the 2 KW sensor that no longer functions.  I'm almost certain that the sensor element got zapped when one of the high power thick film resistors in my homebrew dummy load popped.  The bar graph on the meter now always reads infinite SWR but otherwise seems to work

Re: [Elecraft] W2 wattmeter

Joe, The telling answer is in your statement "the radio has an internal ATU". The radio is showing the SWR between the radio and the ATU. The wattmeter is showing you the SWR after the ATU - in other words, the SWR of the untuned antenna. So there may be nothing wrong. Connect a dummy load

[Elecraft] W2 wattmeter

My wattmeter seems to be displaying the wrong SWR on the LEDs. I bought a digital display unit on line. The radio has an internal ATU. The radio says tuned 1.0 - 1. when I key the radio says 1.0 - 1 and the DDU says .16 SWR but the LEDs show 1.5 - 1. So if I hit 1.2 - 1 the LEDs all flash so

I'm not sure I can explain this. But it's possible the problem is a combination of two possible error sources: 1) I believe the XV50 leds are displaying power based on the voltage at the final stage, and is not using a SWR bridge to measure forward power. The W2 is measuring forward power, so

Re: [Elecraft] W2 Wattmeter

Dick, That is true, but they are often confused - furthermore with any resolution on a display like a bargraph, it is helpful to know to know if the LED illuminates just after the indicated power is reached or at some midpoint value. I don't know, but I suspect that Elecraft has chosen to

Re: [Elecraft] W2 Wattmeter

Sorry, 10 watts below should have been 20 watts for my example. I hope everyone got the point despite my error. 73, Don W3FPR Don Wilhelm wrote: Dick, That is true, but they are often confused - furthermore with any resolution on a display like a bargraph, it is helpful to know to know

Re: [Elecraft] W2 Wattmeter

Don, Those are good points about the trigger and perception of accuracy of the W2. I have yet to see field test data of the W2 in regards to accuracy of the Wattmeter and SWR indications. 73, Dick - KA5KKT __ Elecraft mailing list

Re: [Elecraft] W2 Wattmeter

Those are good points about the trigger and perception of accuracy of the W2. I have yet to see field test data of the W2 in regards to accuracy of the Wattmeter and SWR indications. According to the manual the W2 has an accuracy of +- 0.5dB typical (nothing about worst-case). This is 10-12%

Re: [Elecraft] W2 Wattmeter

I'm very happy with my W2. There was an issue with an intermittent in the sensor cable but that was quickly resolved. It seems accurate enough to me on a subjective basis - I have no Bird to compare it to. As far as resolution goes the computer display resolution does rely on LED's and is a

The FWD and REFL bar indicators have 200 units of resolution compared to only 20 LED's on the W2. Make that 17 LED's on the W2.. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Good evening. I ran into this this morning after building the second W2 here. I have 2 K3's here. One that I use on HF and one that I use on 2m 70cm. Although I can run two instances of W2.exe with each instance connected to each of the two W2's that I have, I'd sure like to be able to name

Why would I need a DCHF-200 coupler if the DCHF-2000 would provide low power readouts? The display unit has the bargraph ranges of 2, 20, 200 and 2000 watts. Why not buy two DCHF-2000 couplers, one between the K3 and linear amp and another between the amp and antenna tuner. This way one of

Hi all, I might be having a blonde moment but I am looking at the W2 and it seems to me that with 2 sensors, it can act as an antenna switch too. Is this the case or am I missing something? 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC HB9DRV-9 DX Clusters Member RSGB, GQRP 9838, FISTS 14077 | K3
